Developing sustainable and efficient methods for the transformation of 1,3-dicarbonyl compounds and alkene functionalization represents a pivotal endeavor for advancing the frontiers of synthetic organic chemistry. Herein, an electrochemically driven functionalization reaction of 1,3-dicarbonyl compounds and alkenes is reported, which enables the efficient construction of α-alkylated 1,3-dicarbonyl compounds. This protocol avoids additional chemical oxidants/reductants, proceeds under mild and environmentally benign conditions, and exhibits excellent functional group tolerance, furnishing a diverse array of target products in moderate to good yields. Mechanistic studies indicate that electrochemically generated 1,3-dicarbonyl radicals add to alkenes, followed by single-electron transfer (SET) oxidation and nucleophilic alcohol quenching, thereby realizing efficient alkene functionalization.
